Application filed December 'To all whom dam-cry concern:

Be it known that I, CALVIN Dozinn, a citizen of the UnitedStates,.residing at Riclr mond,in the county of Madison and State ofKentucky, have invented lcertain new and useful Improvements inShock'Absorbc'rs, of which the following is a specification.

This invention relatesto vehicles, and has special reference to a springsuspension for vehicles- More particularly the" inventionrelates to anovel spring arrangement constituting a shock absorber.

One important object of the invention is to provide an improved generalarrangement of springs for supporting a vehicle on its axle.

second important object of the invention is to provide an improvedspring arrangeinent of this character wherein both the main and theshock absorbing springs will be cantilever sprin A third importantobject of the invention is to provide a novel spring arrangement whereinthe axle has the central portion of a leaf spring connected thereto, theends of said leaf spring-being spring connected respectively to theframe and axle of the ve- With the above and otherobjects in view aswill be hereinafter apparent, the invention consists in general ofcertain novel details of I construction and combinations of partshereafter fully described, illustrated in the accompanying drawings andspecifically claimed. 7 V

In accompanying drawings like characters of reference indicatelike'partsin the several views, and

Fig. 1 is aside elevation showing a por tion of the frame and one axleof a'vehicle provided with this spring arrangement.

Fig. 2 is a section on the line 22 of Fig. 1

Fig. 1. In the embodiment of the invention herein illustrated, thereis'disclosed a portion of a vehicle frame member 10, and to this framemember is secured the butt or large end of a cantilever spring 11 havinga spirally curved end 12, the spring consisting asusual of a 3 is asection on the line 3-8 of plurality of leaves graduated in length so asto produce a tapering of the spring as a whole from butt to the spiralend. This butt end is secured by the usual spring clips 13.

At 14 is a vehicle axle, and this axle ex 1, 1922. Serial No. ceases.

leaf spring 17 which is secured by a bolt 18 passing through the centralpart of a saddle 19 whereto the spring 1? is secured by clip bolts 20.This reversely curved spring is preferably termed a see-saw spring owingto its being secured in the middle and having one end curved up and theother curved down. The upwardly curved end of this spring is connectedto the end 12 of the spring 11 by shackles 21 through which pass theshackle bolts 22.

Between the'eyes 15 is located a saddle 23 which is carried on the axle14 and secured on this saddle is the flat end 24: of a fork 25. On thisflat end2-l is fixed the butt or large end of a cantilever spring 26formed of a plurality of leaves and extending in substan tialparallelismwith the downwardly curved half of the spring 17, theextremities of this downwardly curved half and the spring 26' beingconnected by the shackles 27 and bolts The forward end of the fork 25 ispivoted for vertical swingingmovement to the lower end of a bracketwhich is fixed to the frame member 10 by rivets 30.

. The action of these springs is as follows: A blow on the vehicle'wheelsuch as to move the axle upwardly lifts the free end of the fork 25 andthe yoke 16. This tends to cause tilting of the spring 17 which isyieldably re sisted by the spring 26, thuscausing yielding of thesprings 17 and 11, the various springs reassuming their originalpositions after the passing of-the stresses inducing the diston tion ofthe parts.

There has thus been provided simple and efficient device of the hinddescribed and for the purpose specified.

- It is. obvious that minor changes may be made in the form andconstruction of the invention without departing from the material spiritthereof. It is not, therefore, de sired to confine the invention to theexact form herein shown and described, but it is desired to include allsuch as properly come within the scope claimed.

7 Having thus described the invention what is claimed as new, is: l V

1. The combination with a vehicle frame member and an axle; of acantilever spring having its larger end connected to the frame member, asecond cantilever spring having having its larger end connected to theframe lmember, a second cantilever spring having its'larger endconnected with the axle, and

a tilting member supported intermediate itscnds from said aide andhaving its respective ends connected to the free ends of the respectivesprings. f

2. The combination with a vehicle'frame member and an axle; of acantilever spring its-larger endzconnected with the axle, and a tilting;spring member supported interjmediate its ends from said axle and hav-=its largerend'connected with the axle, and a tilting reversely curvedspring member 7 supported interm diate its ends from said axle andhaving its respective ends con nectcd, to'the free ends of therespective springs. l
